Abstract

To meet the accuracy, integrity, availability, and continuity requirements of the safety critical aviation applications, civil aviation organizations worldwide are implementing Global Navigation Satellite System (GNSS) augmentation systems. One of these systems is the Satellite Based Augmentation System (SBAS). The first SBAS is the Wide Area Augmentation System (WAAS) which was deployed in the U.S. by the Federal Aviation Administration (FAA). It became operational on July 10th, 2003. More significantly, WAAS is the first of many SBASs being implemented. The European Space Agency (ESA) is working on the European Geostationary Navigation Overlay Service (EGNOS) and Japan will deploy the MTSAT-based Satellite Augmentation System (MSAS). Both systems will come on-line within a few years. In 2004, the U.S. Trade and Development Agency (USTDA) awarded a grant to States in the Asia-Pacific Region for the Asia Pacific Economic Cooperation (APEC) GNSS Test Bed demonstration project. This Test Bed project will facilitate the implementation and operation of a satellite based aviation navigation system. There are five funded economies, Indonesia, Malaysia, Philippines, Thailand, and Vietnam, in the APEC GNSS Test Bed. In addition to these funded economies, several non-funded economies have expressed tentative interest in participating. These economies are Australia, Chinese Taipei, Hong Kong China, Korea, New Zealand, and Singapore. This paper investigates the potential vertical guidance performance of this APEC GNSS Test Bed based on the protection level calculation defined in the WAAS MOPS (RTCA DO-229C). The simulation tool in this paper is the MATLAB Algorithm Availability Simulation Tool (MAAST). This paper first investigates the performance of the APEC GNSS Test Bed by modifying the MAAST with reference stations in five funded economies and with a geostationary satellite (GEO) at 135 degrees east. This paper will then include some reference stations in the non-funded economies into the MAAST to examine the possible improvements in the vertical guidance performance of this Test Bed. Furthermore, this paper examines combinations of the modernized GPS and the addition of Galileo to determine what vertical guidance performance this APEC GNSS Test Bed could achieve within Flight Information Regions (FIRs) in Southeast Asia.
